| Abstract: | A nested design was used to analyze the variance of the proportions or percent species composition of shore-zone finfish assemblages in the vicinity of the Millstone Nuclear Power Station in eastern Long Island Sound. The relative importance of five selected shore-zone species was found to be significantly influenced by both station and season within a year. Also included in the nested ANOVA model were effects due to period of plant operation (no units operating, one unit operating and two units operating) and year within period. Neither of these two effects was found to influence the percent species composition. The results of this study suggest that a nested ANOVA of percent species composition can be useful for detecting changes in assemblages of finfish species over time and space. |
